I've installed a new 25 foot 6" liner in my chimney to my steel napoleon, and It works get. My concern is lightning. the other day we had a good storm come through high winds and allot of lighting and it had me thinking. Did I just install a lightning rod at the top of my house. Will the stainless liner attracted lightning. Are we save. I could picture it now. Bust ass getting wood load insert sit and enjoy the heat dooring a lightning storm and Bam zapped buy lighting. Are we all save and should the stoves and inserts be grounded
	
		
			
		
		
	
				
			
	
	
  FWIW, I don't think that there is an issue.  I know there are people that have had them installed for years and no problems.  I have been 2 years lightning free
